Medeco Lock Installation & Rekey in Washington: What to Know First
We provide independent Medeco lock installation & rekey in Washington, with most jobs completed same-day and pricing quoted flat before we dispatch. A typical Medeco deadbolt rekey runs $120-$180; full installation of a new Medeco Maxum or M3 cylinder starts around $220-$340 depending on door prep and hardware condition. We quote the price before the truck moves. That’s just how this should work.
This page is for Washington homeowners who already own Medeco hardware and need it installed, rekeyed, or restored to working order - not for someone shopping brands. If your Medeco key is sticking, you’ve lost a key and need the cylinder repinned, or you’re moving into a home with Medeco locks already on the doors, call us at (888) 545-8474. We’ll give you a straight number and a real arrival window.
How Medeco Products Fail - and How We Fix Them
- Medeco Maxum deadbolts with sticky key rotation. In Washington’s humid summers and cold, dry winters, the dual-locking sidebar mechanism in Maxum cylinders can bind when factory lubricant thickens or attracts dust. We disassemble the cylinder, clean the sidebar channels with a non-residue solvent, and repin with factory-spec bottom pins and top pins - never graphite, which turns to abrasive sludge in Medeco tolerances.
- Medeco M3 keyway with premature wear on the angled cuts. The M3’s slider system depends on precise angles; after roughly 8-12 years of daily use in a Washington home, the key’s milled grooves can wallow out the keyway. We diagnose this with a plug follower inspection - if the wafers are intact, we cut a fresh key to factory depth and spacing; if the slider housing is scored, we replace the cylinder core with an OEM M3 core rather than attempting a salvage that’ll fail again in six months.
- Medeco Biaxial cylinders that “click” but don’t retract. The Biaxial’s rotating pin design is sensitive to tailpiece alignment. In older Washington homes with settled door frames, the bolt can bind against the strike plate and transfer torque back into the tailpiece cam. We shim the strike, check the backset, and if the cam is worn, we install a hardened replacement cam - not a soft aftermarket casting that’ll round off under load.
- Medeco KeyMark cylinders in commercial settings with master key wear. KeyMark’s interchangeable core is built for rapid rekeying, but frequent master key changes in Washington rental properties can mushroom the top pins. We stock factory KeyMark pinning kits and rebuild the core rather than replacing the entire housing, which saves the customer roughly $80-$120 per door.
- Medeco deadbolts with corroded mounting screws after coastal exposure. For Washington homes near the Potomac or with basement doors that see groundwater splash, the standard zinc-plated screws can seize in the door. We extract them without stripping the bore, then install stainless steel replacements with anti-seize compound - a fifteen-minute step that prevents a future destructive removal.
Our Medeco Lock Installation & Rekey Process
- 1
Call and quote. You describe the lock, the key situation, and the door condition. We quote a flat price for the most likely scenario and explain what would change it.
- 2
Dispatch with the right parts. Our technician loads OEM Medeco cylinders, pinning kits, and the correct cam and tailpiece variants for your series - Maxum, M3, Biaxial, or KeyMark. No guessing, no “I’ll be back tomorrow.”
- 3
On-site ID and diagnostics. The technician shows ID at the door, confirms the quote, then disassembles the lock to verify the failure mode. If it’s different from what we discussed, we explain before proceeding.
- 4
Repair or rekey with OEM-first parts. We use Medeco factory pins, springs, and cores when available. If a quality aftermarket alternative meets the same tolerances and costs less, we tell you and let you choose.
- 5
Function test and key verification. Every key is checked for smooth rotation at multiple angles, the bolt is cycled twenty times, and the strike alignment is verified under load.
- 6
Written guarantee and cleanup. You get a printed invoice with the 90-Day Done Right Promise, all keys labeled, and the work area swept. Old parts are left with you if you want them.

FAQs
No - rekeying performed by a qualified locksmith using factory-spec parts does not void Medeco’s limited mechanical warranty. As an independent Medeco service provider, we use OEM pinning components and document the work, so your warranty remains intact. If a previous owner or handyman used incorrect pins or power tools on the cylinder, that’s a different story - we can assess and tell you where you stand. Call (888) 545-8474 for a free evaluation.
Most Medeco rekeys are completed within 45 minutes of our technician arriving, and we offer same-day scheduling for calls placed before 2 PM. For Washington addresses inside the Beltway, we typically arrive within 90 minutes during business hours. After-hours emergency service is available with a live dispatcher - no callback queues. Call (888) 545-8474 to check today’s availability.
Repair if the cylinder body, bolt, and strike hardware are sound - a rekey or cylinder swap costs roughly half of full replacement. Replace if the door bore is damaged, the bolt is corroded, or you want to upgrade from Biaxial to M3 for the added pick resistance. We’ll show you both options and the exact price difference, no pressure either way. Call (888) 545-8474 for an upfront comparison.
We stock common Medeco Maxum and M3 cylinders, pinning kits, and key blanks for same-day service. Less common Biaxial cores and KeyMark master systems may require next-day ordering, but we’ll tell you during the phone quote - no surprises when we arrive. For urgent situations, we can install a compatible temporary lock from our Schlage or Kwikset inventory while your Medeco part comes in. Call (888) 545-8474 to confirm stock for your series.
The sidebar and pin tolerances in Medeco cylinders are tight enough that thermal contraction of the brass plug and steel sidebar can increase friction below 35 degrees. Combined with Washington’s dry winter air, any residual lubricant can gum or crystallize. We disassemble, clean with solvent, and apply a PTFE-based dry lubricant formulated for high-security tolerances - not WD-40, which attracts dust and worsens the problem. Call (888) 545-8474 to schedule before the next cold snap.
